i ordered fryers for 120/240 volt (208 volt high leg) 3 phase delta systems... the manufacturer gave me the three phase 120/240 volt rated equipment and told me that they have never heard of a high leg, im confused. is this equipment going to be ok? i don't understand.

On the high leg delta you will have one leg that reads 208 to ground this could pose a problem with the 120V portion of the equipment as for phase to phase you will have 240V
 
Seems like you're missing some information from the manufacturer. IMO a 120/240 volt appliance would be fed from a single phase system. Also just for clarity a 208 volt system is a Wye system not a Delta.

A high leg Delta is configured with one leg 208V to ground

Yes, it makes much more sense now that Kmalsam has edited his OP.

Kmalsam please try to avoid editing your posts to the point where it changes the content. It makes it difficult to follow because some of the answers are based on your original post. If you do need to edit a post post a new reply with the explanation of the correction first.

Thanks.:cool:

Find another technician to talk to at the manufacturer that understands 3PH Delta? Sometimes they have experienced field techs.

A quick look at the *Frymaster* (better brand and very common maker) website indicates they spec a separate 120V line for controls on their 3 phase equipment. It also indicates that they at least are aware of the various 3 phase voltage possibilities available.

(if I knew how to copy and paste out of pdf files I'd have done it)
